Announcing UniformStreamlines.jl, a lightweight Julia package for generating and plotting evenly spaced streamlines in 2D, 3D, and N-D vector fields using the Jobard–Lefer algorithm.

It works with both function-defined and grid-defined velocity fields, and supports plotting with both Plots.jl and Makie.jl.

Features include:

- streamline generation in 2D, 3D, and N-D
- support for function- or grid-defined fields
- coloring, arrows, seed points, and NaN masking
- plotting support for Plots.jl and Makie.jl
